Microsoft kicks out fix for buggy Win Server 2012 WSUS updates

Patch aims to alleviate issues with unpacking downloads


Microsoft has a released a fix to address problems with its Windows Server Update Services (WSUS) tool. For those not in the know, WSUS is a component of Windows Server that lets IT administrators push particular updates to users' PCs.

Redmond said installing KB3159706 on Windows Server 2012 will give WSUS the ability to automatically decrypt upgrades from Microsoft in the same way client-side Windows Update software does. WSUS defines "upgrades" as feature additions, separate from "updates" that typically include security patches.

This, Microsoft hopes, will eliminate some of the problems that have been plaguing recent WSUS channel upgrades for Windows 10 machines delivered through Windows Server 2012/R2 with the KB3148812 patch.

Microsoft says that WSUS machines had been unable to properly decrypt the upgrade files which in turn caused problems when the upgrades were pushed out to the end users.

"Until now, we have been manually decrypting these packages prior to releasing to the WSUS channel, the process of which is both time consuming and error prone," explained Windows Server program manager Steve Henry.

"KB3159706 introduces this functionality to WSUS for Windows Server 2012/R2, such that it can now natively decrypt this content."

All administrators running WSUS should install the fix, as the ability to download and distribute future Windows 10 upgrades will depend on it being present. The update will be installed by default on Windows Server 2016 releases.

Microsoft notes that WSUS admins may want to manually remove the KB3148812 patch before installing, though the new update should be able to automatically replace the old and removal is considered "optional." ®

  • Meet Wizard Spider, the multimillion-dollar gang behind Conti, Ryuk malware
    Russia-linked crime-as-a-service crew is rich, professional – and investing in R&D

    Analysis Wizard Spider, the Russia-linked crew behind high-profile malware Conti, Ryuk and Trickbot, has grown over the past five years into a multimillion-dollar organization that has built a corporate-like operating model, a year-long study has found.

    In a technical report this week, the folks at Prodaft, which has been tracking the cybercrime gang since 2021, outlined its own findings on Wizard Spider, supplemented by info that leaked about the Conti operation in February after the crooks publicly sided with Russia during the illegal invasion of Ukraine.

    What Prodaft found was a gang sitting on assets worth hundreds of millions of dollars funneled from multiple sophisticated malware variants. Wizard Spider, we're told, runs as a business with a complex network of subgroups and teams that target specific types of software, and has associations with other well-known miscreants, including those behind REvil and Qbot (also known as Qakbot or Pinkslipbot).

  • Supreme Court urged to halt 'unconstitutional' Texas content-no-moderation law
    Everyone's entitled to a viewpoint but what's your viewpoint on what exactly is and isn't a viewpoint?

    A coalition of advocacy groups on Tuesday asked the US Supreme Court to block Texas' social media law HB 20 after the US Fifth Circuit Court of Appeals last week lifted a preliminary injunction that had kept it from taking effect.

    The Lone Star State law, which forbids large social media platforms from moderating content that's "lawful-but-awful," as advocacy group the Center for Democracy and Technology puts it, was approved last September by Governor Greg Abbott (R). It was immediately challenged in court and the judge hearing the case imposed a preliminary injunction, preventing the legislation from being enforced, on the basis that the trade groups opposing it – NetChoice and CCIA – were likely to prevail.

    But that injunction was lifted on appeal. That case continues to be litigated, but thanks to the Fifth Circuit, HB 20 can be enforced even as its constitutionality remains in dispute, hence the coalition's application [PDF] this month to the Supreme Court.

    FBI and co blow lid off latest PHP tampering scam

    The FBI and its friends have warned businesses of crooks scraping people's credit-card details from tampered payment pages on compromised websites.

    It's an age-old problem: someone breaks into your online store and alters the code so that as your customers enter their info, copies of their data is siphoned to fraudsters to exploit. The Feds this week have detailed one such effort that reared its head lately.

    As early as September 2020, we're told, miscreants compromised at least one American company's vulnerable website from three IP addresses: 80[.]249.207.19, 80[.]82.64.211 and 80[.]249.206.197. The intruders modified the web script TempOrders.php in an attempt to inject malicious code into the checkout.php page.
